Meth not even once - Halloween pumpkin edition. Crystal meth is short for crystal methamphetamine. It is just one form of the drug methamphetamine.
Methamphetamine is a white crystalline drug that people take by snorting it (inhaling through the nose), smoking it or injecting it with a needle. Some even take it orally, but all develop a strong desire to continue using it because the drug creates a false sense of happiness and well-being—a rush (strong feeling) of confidence, hyperactiveness and energy. One also experiences decreased appetite. These drug effects generally last from six to eight hours, but can last up to twenty-four hours.
